Inventor: HIRABAYASHI KAZUYA
IPC: G05B23/02
Filed: 1995-03-01
Abstract: PURPOSE: To apply a water distribution quantity predicting method even if the number of data is small and quickly respond to the changes of the environment by determining the predicted value of the periodic fluctuation component of the distribution quantity, determining the remainder component except the fluctuation component with a self-regression model, and using the sum of two predicted values as the distribution quantity predicted value. CONSTITUTION: Water is distributed from a distributing reservoir 1 via natural flow-down. The distribution flow is detected by a distribution detector 2, and the actual result, weather, predicted weather, and predicted temperature are inputted to an input device. The input data collected by a measured value storage device 5 are accumulated, and average fluctuation patterns for the day of the week, time, and weather are generated by an average fluctuation pattern generating device 6. The correction coefficient for the rainy day is determined by a correction coefficient generating device 7 based on the ratio between the average values of the distribution quantities on rainy days and on days other than rainy days in the past.  The stored measured value of the measured value storage device 5, the average fluctuation pattern of the average fluctuation pattern generating device 6, and the correction coefficient are inputted to a system variable data generating device 8, and the data excluded with the effect of weather and day of the week and the system variable data of temperature are generated.

Title: D/a converter
Inventor: SUZUKI MASAO
IPC: H03M1/66
Filed: 1990-03-19
Abstract: PURPOSE:To decrease the number of externally mounted components and an inter-channel offset having been a problem in the case of use of plural D/A converters by unifying a D/A converter and a reference power supply in one chip, and providing separately an output terminal of the reference power supply and an input terminal for setting output amplitude. CONSTITUTION:The Figure shows a circuit diagram in the case of using three sets of D/A converters. Voltages VRT, VRB depending on a reference power supply built in a D/A converter 1 in (A) are applied respectively to output amplitude setting terminals VFS, VZS of each D/A converter 1 of the sets (A), (B), (C) to decide the output amplitude. In such a case, since the setting voltage and the output amplitude depend on a resistance ratio inside of an IC, an inter-channel offset among the D/A converters 1 of the sets (A), (B), (C) is theoretically zero. Moreover, a current IRT supplied from the built-in reference power supply of the D/A converter 1 of the set (A) is I1X3because a current I2 flowing to current SW is supplied from the inside of each A/D converter 1. The current I1 is sufficiently smaller than the current I2, the current capacity of the reference voltage source is enough to be small and the wire resistance causes no problem.

Title: Embedded type zener diode
Inventor: YOSHIKAWA TAKEO
IPC: H01L29/866
Filed: 1985-04-02
Abstract: PURPOSE:To stabilize breakdown voltage and to decrease breakdown noise, by providing a structure, in which a breakdown junction plane is made to be a unitary body, and providing a structure, in which said junction plane is provided at a position that is separated from the surface of a substrate by a long distance. CONSTITUTION:A P-N isolating diffused region 5 is formed, and a P<+> type isolating diffused region 6 is simultaneously formed in an N-type epitaxial growing layer 3. A P<+> type base diffused region 7 is formed so as to hold the P<+> type isolating diffused region 6 at the center. P<+> type graft base diffused regions 16 are formed at two positions in the P<+> type base diffused region 7. The positions are located in the deep parts, which are separated from the P<+> type isolating diffused region 6 and from the surface of a semiconductor by a long distance, so that the regions 16 are not overlapped at the bottom part of the P<+> type base diffused region. Thus the breakdown voltage becomes approximately constant. Since the breakdown point is located in the deep part in the semiconductor, the effect of the interface between the semiconductor and the oxide film is hard to receive. Therefore, the Zener voltage is stable. Since the breakdown occurs in the deep part of the semiconductor, the avalanche noise and the Zener noise are small.

Abstract: PURPOSE:To damp a slapping noise generated from a piston, by arranging such that a piston pin and a piston gravity center are respectively offset from a center of piston in the direction of piston, and the piston gravity center is more offset than a magnitude of offset of the piston pin. CONSTITUTION:A piston 11 is provided with a piston boss 12 engaging a piston pin therein, and the piston boss 12 has its center 13 offsetted from a center 14 of the piston 11 in the direction of thrust by a distance DELTA1.

A magnitude of this offset is made greater than that of the pin boss 12. In this manner, moments of a gas pressure and of inertia force of the piston are effected in the reverse directions each other and thus a slapping sound of the piston can be damped in all rotating ranges.
